Ong Bak was sadly never collected before succumbing to serious  injury.  Grassbrook have retained a small number of his female progeny, and  the first of those to produce, gave us Grassbrook Shadrach with whom we are exceedingly pleased. 
We look forward to foals from suitable stallions out of Grassbrook Gunhilde, Grassbrook Seraphina, and Grassbrook Yalda Ketana, when the time is right, into the future.
